Try Geneclean (from Q-Biogene). Always found it reliable, and it
gives reasonable yield, unlike Qiagen which I found to be unreliable
(sometimes good, but sometimes shitty yield especially for small
fragments). Geneclean also has the Mermaid kit which is specifically
designed for very small fragments, but this is not necessary for
200bp. We recently tried purifying a 150 bp PCR product and got
reasonable good yield from both the Geneclean Turbo and Mermaid kits.
You can purify directly from the PCR reaction or from agarose gel.
